Demonstrators marched on Saturday to protest the police killing of a 19-year-old unarmed black man in Madison, Wisconsin, a shooting that came amid growing scrutiny of law enforcement's use of lethal force against minorities, the poor and mentally ill. Chanting "the whole damn system is guilty as hell," hundreds of protesters walked peacefully from police headquarters in the state capital to the neighbourhood where the young man was shot by police on Friday evening.
They carried a banner reading "Black Lives Matter" that stretched the width of the street and signs that read "Justice 4 Tony" and "5 Shots 5 Times Unacceptable."
The shooting occurred after a police officer responded to calls reporting a man was dodging cars in traffic and had battered another person, Madison Police Chief Mike Koval said.
The officer followed the suspect into an apartment, was struck in the head and shot the teen, who died later at a hospital, Koval said.
Koval said the victim, identified as Tony Robinson Jr., did not have a weapon.
